(C)any member of a class of plaintiffs is a citizen of a State and any defendant is a foreign state or a citizen or subject of a foreign state.

(3)A district court may, in the interests of justice and looking at the totality of the circumstances, decline to exercise jurisdiction under paragraph (2) over a class action in which greater than one-third but less than two-thirds of the members of all proposed plaintiff classes in the aggregate and the primary defendants are citizens of the State in which the action was originally filed based on consideration of—

(A)whether the claims asserted involve matters of national or interstate interest;

(B)whether the claims asserted will be governed by laws of the State in which the action was originally filed or by the laws of other States;

(C)whether the class action has been pleaded in a manner that seeks to avoid Federal jurisdiction;

(10)For purposes of this subsection and section

(11)

(A)For purposes of this subsection and section
1453, a mass action shall be deemed to be a class action removable under paragraphs (2) through (10) if it otherwise meets the provisions of those paragraphs.

(B)

(i)As used in subparagraph (A), the term “mass action” means any civil action (except a civil action within the scope of section
1711(2)) in which monetary relief claims of 100 or more persons are proposed to be tried jointly on the ground that the plaintiffs’ claims involve common questions of law or fact, except that jurisdiction shall exist only over those plaintiffs whose claims in a mass action satisfy the jurisdictional amount requirements under subsection (a).

(ii)As used in subparagraph (A), the term “mass action” shall not include any civil action in which—

(II)the claims are joined upon motion of a defendant;

(III)all of the claims in the action are asserted on behalf of the general public (and not on behalf of individual claimants or members of a purported class) pursuant to a State statute specifically authorizing such action; or

(I)to cases certified pursuant to rule 23 of the Federal Rules of Civil Procedure; or

(II)if plaintiffs propose that the action proceed as a class action pursuant to rule 23 of the Federal Rules of Civil Procedure.

(D)The limitations periods on any claims asserted in a mass action that is removed to Federal court pursuant to this subsection shall be deemed tolled during the period that the action is pending in Federal court.

(e)The word “States”, as used in this section, includes the Territories, the District of Columbia, and the Commonwealth of Puerto Rico.

Other provisions of section
41(1) of title
28, U.S.C., 1940 ed., are incorporated in sections
1331,
1341,
1342,
1345,
1354, and
1359 of this title. (See reviser’s notes under said sections.)

Jurisdiction conferred by other sections of this chapter, except section
1335, is not dependent upon diversity of citizenship. (See annotations under former section
41 of title
28, U.S.C.A., and 35 C.J.S., p. 833 et seq. §§ 30–43. See, also, reviser’s note under section
1331 of this title.) As to citizenship of bank where jurisdiction depends upon diversity of citizenship, see section
1348 of this title.

Words “all civil actions” were substituted for “all suits of a civil nature, at common law or in equity” in order to conform to Rule 2 of the Federal Rules of Civil Procedure.

Words “or citizens of the District of Columbia, Territory of Hawaii, or Alaska, and any State or Territory” which were inserted by the amendatory act April 20, 1940, are omitted. The word “States” is defined in this section and enumeration of the references is unnecessary.

The revised section conforms with the views of Philip F. Herrick, United States Attorney, Puerto Rico, who observed that the act of April 20, 1940, permitted action between a citizen of Hawaii and of Puerto Rico, but not between a citizen of New York and Puerto Rico, in the district court.

This changes the law to insure uniformity. The 1940 amendment applied only to the provision as to controversies between “citizens of different States.” The new definition in subsection (b) extends the 1940 amendment to apply to controversies between citizens of the Territories or the District of Columbia, and foreign states or citizens or subjects thereof.

The diversity of citizenship language of section
41(1) of title
28, U.S.C., 1940 ed., as amended in 1940, was described as ambiguous in McGarry v. City of Bethlehem, 45 F.Supp. 385, 386. In that case the 1940 amendment was held unconstitutional insofar as it affected the District of Columbia. However, two other district courts upheld the amendment. Winkler v. Daniels, D.C.Va. 1942, 43 F.Supp. 265; Glaeser v. Acacia Mutual Life Ass’n., D.C.Cal. 1944, 55 F.Supp. 925.

This section is intended to cover all diversity of citizenship instances in civil actions in accordance with the judicial construction of the language in the original section
41(1) of title
28, U.S.C., 1940 ed. Therefore, the revised language covers civil actions between—

Citizens of a State, and citizens of other States and foreign states or citizens or subjects thereof;

Citizens of a Territory or the District of Columbia, and foreign states or citizens or subjects thereof;

Citizens of different States;

Citizens of different Territories;

Citizens of a State, and citizens of Territories;

Citizens of a State or Territory, and citizens of the District of Columbia;

Citizens of a State, and foreign states or citizens or subjects thereof.

The revised section removes an uncertainty referred to in the McGarry case, supra, as to whether Congress intended to permit citizens of the Territories or the District of Columbia to sue a State or Territory itself rather than the citizens thereof. The court observed that “Congress could hardly have had such intention.”

The sentence “The foregoing provisions as to the sum or value of the matter in controversy shall not be construed to apply to any of the cases mentioned in the succeeding paragraphs of this section” was omitted as unnecessary. Those paragraphs are (2)–(28) of said section
41 of title
28, U.S.C., 1940 ed., which are revised and incorporated in this chapter and, except for those relating to actions against the United States and interpleader, contains no provision as to a sum or value necessary to confer jurisdiction. Consequently the omitted sentence is covered by excluding such requirement.

Section
41(1) of title
28, U.S.C., 1940 ed., as originally enacted, purported to include all jurisdictional provisions relating to the district courts. Subsequently, many special jurisdictional provisions were enacted and incorporated in other titles of the U.S.C., 1940 ed., as follows:

Rule 23 of the Federal Rules of Civil Procedure, referred to in subsec. (d)(1)(B), (11)(C)(ii), is set out in the Appendix to this title.
